Intraoperative Transducers
➤ To perform Test 1—Transducer Leakage Current Test (Source)
1. Plug the safety analyzer into the power source.
2. Plug the ultrasound system into the safety analyzer.
3. Connect the transducer being tested to the ultrasound system.
4. Immerse 5 cm (2 in) of the transducer in the saline solution.
5. Set the safety analyzer Mode switch to the ECG position.
6. Set the safety analyzer Leads switch to the ALL (all ECG leads) position.
7. Connect a lead to any ECG terminal on the safety analyzer and immerse the
other end into the saline solution.
WARNING
Electrical Shock Hazard: Do not touch the lead that was connected to the
safety analyzer in step 7.
8. Set the safety analyzer Line Polarity switch to Normal.
9. Note the normal condition leakage reading.
10. Press and hold the safety analyzer Ground Open switch in the Open posi-
tion (Single Fault condition), and note the leakage reading on the output dis-
play.
11. Repeat step 9 and step 10 with the Polarity switch in the Reverse position.
The applicable limits are
– 10 µA RMS (normal condition)
–50 µA RMS (Single Fault condition)
